In a sense, we are trying to implement Granger’s original idea of causality.1 It is worth relating our work to the existing literature on Granger causality with high- WebJun 29, 2024 · When testing for Granger causality: We test the null hypothesis of non-causality ( H 0: β 2, 1 = β 2, 2 = β 2, 3 = 0). The Wald test statistic follows a χ 2 distribution. We are more likely to reject the null hypothesis of non-causality as the test statistic gets larger. We should test both directions X ⇒ Y and X ⇐ Y.
